Selena spent her birthday, July 22, on a yacht with Cara Delevingneand her rumored new beau, Tommy Chiabra but the fun didn’t stop there.

Selena Gomez & Cara Delevingne’s Wild Night With Robin Thicke

In our exclusive video, you see Robin singing his hit song, “Blurred Lines,” and then Cara and Selena hop on the stage. You see Cara start walking over to Robin but then she gets a little shy and retreats to the side of the stage where Selena is breaking it down. We would totally jump on stage if Robin was singing that song too!

But they were partying for a good cause, the glamorous event raised over $25 million for The Leonardo DiCaprio Foundation, whose mission it is to protect wildlife all over the world.

In this video, Selena is wearing her second outfit of the night! Selena arrived to the event in a thigh-high gown and then changed into this black little number with a matching veil!

It was quite the star studded night — Marion Cotillard, Bono, Petra Nemcova, Lauren Rae Levy and more were in attendance.

Selena & Tommy Chiabra — The Truth Behind Their Romance

We told you that Cara actually introduced Selena to Tommy. The Royal Yacht owner, was spotted riding around on jet skis with Selena on her birthday, alongside their mega-yacht. They cuddled and even held hands at one point!

But Selena still has feelings for Justin, according to our source. We aren’t surprised but were happy to see her at least attempting to try and move on.

“She’s having fun, she’s not ready for anything serious right now,” our source told us. “It’s all just for fun. Tommy isn’t the only guy she’s talking to, she’s keeping her options open. She says she’s going to stay single for a while, she wants to focus on herself.”

Just one week after Selena’s birthday, Justin and Orlando Bloom got in to a huge fight, July 30, at Cipriani in Ibiza. Justin reportedly said something about Orlando’s estranged wife, Miranda Kerr, and that’s when Orlando jumped over a couch and tried to punch Justin in the face. Luckily, Selena had already flown him to LA before this overseas craziness ensued!
